Objective To observe the effects of parecoxib sodium on laparoscopic cholecystectomy ( LC ) patients after remifentanil fast track anesthesia.Methods 120 patients underwent general anesthesia for laparoscopic cholecystectomy were divided into two groups using random number table,60 cases in each group.The observation group was injected parecoxib sodium 40mg+saline solution 5 mL,while the control group was injected only saline so-lution 5mL prior to induction of anesthesia.The heart rate,mean arterial pressure,awaked time,pain score,agitation score and adverse reaction were compared.Results 5, 15, 30min after extubation, heart rate were ( 75.7 ± 4.8)times/min,(79.3 ±6.2)times/min,(74.2 ±5.2)times/min in the observation group and (85.2 ±3.8)times/min, (88.2 ±5.9)times/min,(86.1 ±6.2)times/min in the control group,and the mean arterial pressure were (103.5 ± 11.3)mmHg,(104.7 ±12.6)mmHg,(108.4 ±12.7)mmHg in the observation group and (132.3 ±16.3)mmHg, (135.2 ±14.6) mmHg,(133.6 ±11.8) mmHg in the control group,there were statistifically significant differences (t=4.722,4.357,4.236,4.732,4.367,4.063,all P <0.05).The pain score,agitation score were (2.5 ± 0.9)points,(1.4 ±0.8) points in the observation group,which were lower than (4.2 ±1.2) points,(3.2 ± 1.2)points in the control group(t =4.232,5.234,all P<0.05).Conclusion Parecoxib sodium can reduce the fast-track anesthesia agitation and pain,improve hemodynamics and stress response in LC patients.

Objective: By building database model, to put forward measures to solve the shortage of basic drugs. Methods: There were five factors influencing medicine shortage have been researched, collecting data, using SPSS 18.0 software to build the database model of different parts, and then analyzed the existing problems and inner link, scientifically came up with the basic framework and main solutions of guarantee measures on shortages of essential medicines. Results: The database model of country and six areas in it have been built, and the influence factors of drug shortage in different region have been analyzed, and raised five aspects measures to secure reliable supplies of drugs, including selection, bid and procurement; production and flow; reserve and adjust;pricing and pay;use training. Conclusion: This study extends the application of database, enriches research ideas of drug policy, and the policy put forward to avoid drug shortages to a certain extent.
